The atmospheric degradation of 1-bromopropane (CH3CH2CH2Br): The photochemistry of bromoacetone
نویسندگان
چکیده
[1] The atmospheric degradation of 1-bromopropane and its degradation products are examined with respect to their ability to deplete stratospheric ozone. It is shown that the OH initiated oxidation of 1-bromopropane does not lead to long lived bromine containing species. Laboratory measurements of the UV absorption cross sections and photodissociation quantum yields of chloroacetone and bromoacetone are presented. The atmospheric photolysis lifetime of bromoacetone at mid-latitudes is determined to be on the order of hours.

The use of colored semiconductor oxide like copper (II) oxide and nickel (II) oxide for photocatalytic bleaching of rose bengal was investigated in detail. In order to harness the solar energy, the effective wavelength of the photocatalyst is to be expanded into the visible region and that increases the rate of photocatalytic bleaching of the dye.

متن کاملRaman Study of the Photochemistry of Maleic Acid Adsorbed on the Surface of Colloidal Silver
The surface-enhanced Raman scattering (SERS) spectra of maleic (cis; 2-butaneoic acid) and fumaric (trans; 2-butaneoic acid) acids adsorbed on aqueous silver sol particles are reported. These two acids form two groups of isomers which differ only in the relative positions of the two carboxylate groups. The photochemistry of maleic and fumaric acids adsorbed on the surface of silver colloids...
